MACHINE FOR FORMING TUFTED UPHOLSTERY.

SPECFICATION forming part of Letters 1atent No. 631,551, dated August22, 1899. Application iiled February 1'7. 1899, Serial No. '705,765l (N0model.)

. is a full and exact description thereof, reference being had to theaccompanying drawings, making part of this specification.

Our invention relates to machines for forming tufted upholstery; and ithas for its object the improvement in the construction of such machines,whereby they are simplifiedand rendered more efficient in action.

The novelty of our invention consist-s in the combination andsubcombination of the parts, as will be hereinafter set forth, andspecifically pointed out in the claims.

In the accompanying drawings, Figure l is a front elevation of amachine'for forming tufted upholstery embodying our invention. Fig. 2isa plan view'of the top pressure-frame. Fig. 3 is a section on line 3 3of Fig. 2. Fig. 4.- is an end elevation of Fig. l, looking toward theleft. Fig. 5 is a plan view of the lower pressure-frame with clampingdevice removed. Fig. 6 is a detail showing a plan view of a cross-barvof lower pressure-frame. Fig. 7 is a Ivertical section throughcross-bar of lower pressure-frame, tuCking-tube, quillholder, andfilling ,guard-iinger, the quill showing in side elevation. Fig. 8 showsa side elevation of the clamping device.

Similar letters of reference indicate like parts throughout the severalviews of the drawings.

The frame which supports the mechanism of my device comprises thefourvertical posts and longitudinal and transverse framing A, the exactconstruction of which frame is immaterial so long as it is sufficientlystrong and rigid to stand'the strain which it will becalled upon tobear. Attached to the upper transverse pieces of the frame is a shaftA15,supplied with proper bearings. The outer ends of the shaft havesecured to them sprocket-wheels. The lower transverse pieces of theframe have also attached to them apiece of shafting A15, supplied withproper bearings and having sprocket-wheels attached to the ends, so thatthey will be in line with the sprocket-wheels onthe upper shaft A111.Passing around the sprocket-wheels attached to the shafting A11 and A15are sprocket-chains A3 and A4, and secured to these sprocket-chains is acrossbar A2, so that when the sprocket -wheels which are attached to theabove-mentioned shafting are revolved by means of the handwheel A12 theycause the aforesaid cross-bar to ascend or descend,'owing to thedirection in which the hand-wheel A12 is turned. Attached to the stud onwhich the hand-wheel A12 is secured is a pinion A11, which transmitspower and motion to the gear A14, the gear A14 being attached to thelower shaft A15, to which the sprocket-wheels are attached that transmitmotion,throu gh the sprocket-chains, to the upper shaft A16. Attached tothe stud A9, in addition to the hand-wheel A12 and pinion A11, are aratchet-wheel A10 and a pawl A15, the ratchet-Wheel and pawl being forthe purpose of holding the hand-Wheel A12 in any position desired. Theupper pressure-frame B is arranged so as to readily be attached to ordetached from the cross-bar A2. The lower pressure-frame C is attachedto the frame A by two gudgeons, which' project from the end of thecenter of the frame, the gudgeons revolvin g in suitable bearings whichare attached to the frame A.

The upper pressure-frame is Constructed as follows: The two side barsare made of angle-iron of any suitable size, provided with cross-bars B4and B5, bolted to the angle-iron at the ends. The cross-bars B6 areadjustable and when placed in the position desired for the class of workthat the operator may desire to do are held in position by means'of thelongitudinal slotted pieces B7 and B8,

`which are held firmly against the cross-bars B6 by the clamps B9. Tofurther aid in holding the cross-bars B6 in position the under sidesofbothends of the bars B6 have a piece of rubber-B10 attached to them.Running lengthwise with the upper pressure-frame are adjustable thinstrips B11, vof'any desirable material and also any suitable width. Thestrips B11 are' bent up and over theend pieces B4 and B5, and the spacesbetween the crossbars B6 and strips B11 can be made any size desiredwithin the limit of the frame.

The lower pressure-frame is constructed the IOO same as the upperpressure-frame except that the lower pressure-frame has no longitudinalthin strips and the adjustable cross-bars C2 are made as shown in Figs.6 and 7. The gaining out of the lower side of the cross-bar C2, asshown, is for the purpose of providing a recess for the nut C, whichprevents the nut from turning.

Attached to the sides of the lower pressureframe are arms C" and C11.The arms C11 have eccentrics C12 attached to their lower ends, which areused for clamping the quillsupport board D to the lower pressure-frame.The upper ends of arms Cl1 are pivoted to the sides of the lowerpressure-frame. The lower ends of arms (l9 are pivoted to the sides ofthe lower pressure-frame and have eccentrics C10 attached to their upperends for clamping the upper pressure-frame to the lower pressure-frame.

The adjustable cross-bars C2 of the lower pressure-f rame have ing-tubesCssecu red to them by nuts C5 and CG. To hold the quill C7 central inthe tucking-tube C3, we have a quill-support C4. The quill C7 isprevented from falling through the quill-support C4 by the quill-supportboard D. All the tools used for the different classes of upholsteringwhich can be made on our machine are attached to the adjustablecross-bars C2 of the lower pressure-frame C.

Vhen it is necessary to change the position of the tucking-tubes C2 tosuit the different sizes of tufts, the upper nut C5 is loosened, andthen the tucking-tube can be slid along the bar C2 to any desiredposition, when the nut C5 is tightened down onto the bar C2, holding thetucking-tube securely in position.

lVhen it is desirable to sew the buttons on leather upholstering work,it is accomplished in the following manner: The quills are provided witheyes, as shown in Fig. 7. Through the eye of the quill twine is passedwith a button attached to it. The quill in passing up through theleather carries the twine with it, so that the button can be pulled upsolid and the twine secu red to the back of the cushion. \Vhen buttonsare attached to the cushion with twine, it is not necessary to turn thelower pressure-frame over.

The operation of our machine as generally used is as follows: Thequill-holders are placed in the ti1cking-tubes,\vlien the leather orother material (which has been previously marked off for the class ofwork desired) is placed over the tucking-tubes and the quills pushedthrough the leather at the points where the buttons are to be placed.Then the quills are pushed down through the openings in thequill-supports until the quills lower ends rest on the quill-supportboard, the quills being long enough to still project above the tops ofthe tucking-tubes. The filling guard-fingers CS are now placed over thequills, the filling is placed in the spaces between the fillingguard-fingers to the desired depth, the filling guard-fingers areremoved, and the backing is placed over the filling. The upperpressure-frame is now lowered by means of the gearing and sprocket chainand pressed down tightly until the backing is resting on thetucking-tubes, the quills projecting above.

The clamping device (shown in Fig. S) is now placed in position and theupper pressure-frame clamped to the lower pressureframe. The upperpressure-frame is now detached from the cross-bar A2 and the bar raisedu p again out of the way. The support A1T is turned down to allow therevolving of the work, which places the quill-support board D on top.The clamps which hold the quillsupport board D in position are removedand the quill-support board raised out of place by lowering thecross-bar A2, attaching the board to the bar A2, and raising it up highenough so that it will not interfere with the operator working over theframes. The quill-supports are removed, leaving the quills still inposition. The tangs of the buttons are inserted in the quills, when thequills are pushed down through the tucking-tubes with the buttons stillin them. After the buttons have entered the tucking-tubes thedrill-supports are placed against the buttons and the buttons are pushedthrough the tucking-tubes until the quill-holders are in the sameposition they were before being removed from the tuckingtubes. Thequill-support board is now lowered and clamped in position as it wasoriginally, the quills falling to the floor. The work is now revolvedback to its original position, the tin backs placed on the buttons, thetangs fastened down, and the upper pressureframe removed. The completedwork is now removed, and the machine is in position for the operator toproceed with another piece of work.

Vith our machine it is possible, on account of the ad justive feature ofthe pressureframes, to do several pieces of work of different-sizedtufts at the same time.
